   1 splitIndex.maxPercentChange::
   2         When the split index feature is used, this specifies the
   3         percent of entries the split index can contain compared to the
   4         total number of entries in both the split index and the shared
   5         index before a new shared index is written.
   6         The value should be between 0 and 100. If the value is 0 then
   7         a new shared index is always written, if it is 100 a new
   8         shared index is never written.
   9         By default the value is 20, so a new shared index is written
  10         if the number of entries in the split index would be greater
  11         than 20 percent of the total number of entries.

  14 splitIndex.sharedIndexExpire::
  15         When the split index feature is used, shared index files that
  16         were not modified since the time this variable specifies will
  17         be removed when a new shared index file is created. The value
  18         "now" expires all entries immediately, and "never" suppresses
  19         expiration altogether.
  20         The default value is "2.weeks.ago".
  21         Note that a shared index file is considered modified (for the
  22         purpose of expiration) each time a new split-index file is
  23         either created based on it or read from it.
